Ctrl + Tab

Hi,

is there a way by Ctrl + Tab to move focus out of the RadGridView?
I already use CustomKeyboardCommandProvider with success for return key, but I'm not able to use it for Ctrl + Tab, assumed that is the right way.

Thanks in advance.

Dynamic DataFormatString binding using converter does not work

Hi Telerik team,

I have a project with a requirement to display numeric value depending on dynamic unit format in radgridview or radtreelistview.

I bind my radtreelistview to list of object from class below =>
for example : ObservableCollection<MyVariable> obj = new ObservableCollection<MyVariable>();
radTreeListView1.ItemsSource = obj;

public class MyVariable : ViewModelBase, INotifyPropertyChanged

{

public string Name { get; set; }

public CellValue First { get; set; }

public CellValue Second { get; set; }

public CellValue Third { get; set; }

public string Remarks { get; set; }

public ObservableCollection<MyVariable> ChildCollection { get; set; }

}

public class CellValue : INotifyPropertyChanged

{

public string Key { get; set; }

public double? Value { get; set; }

public string Unit { get; set; }

public string Location { get; set; }

public bool IsEditable { get; set; }

}

below is my xaml code for the grid.

<telerik:RadTreeListView x:Name="radTreeListView1" AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed" RowLoaded="radTreeListView1_RowLoaded" RowIsExpandedChanging="radTreeListView1_RowIsExpandedChanging">

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding ChildCollection}" />

</telerik:RadTreeListView.ChildTableDefinitions>

<telerik:RadTreeListView.Columns>

<telerik:GridViewDataColumn Header="Parameters" DataMemberBinding="{Binding Name}" IsReadOnly="True" Width="auto" />

<telerik:GridViewDataColumn Header="First Value" DataMemberBinding="{Binding First.Value, Mode=TwoWay}" DataFormatString="{Binding First.Unit, Converter={StaticResource numberConverter}}" IsReadOnlyBinding="{Binding First.IsEditable}" CellStyleSelector="{StaticResource cellStyle}" Width="auto" />

<telerik:GridViewDataColumn Header="Second Value" DataMemberBinding="{Binding Second.Value, Mode=TwoWay}" DataFormatString="{Binding Second.Unit, Converter={StaticResource numberConverter}}" IsReadOnlyBinding="{Binding Second.IsEditable}" CellStyleSelector="{StaticResource cellStyle}" Width="auto" />

<telerik:GridViewDataColumn Header="Third Value" DataMemberBinding="{Binding Third.Value, Mode=TwoWay}" DataFormatString="{Binding Third.Unit, Converter={StaticResource numberConverter}}" IsReadOnlyBinding="{Binding Third.IsEditable}" CellStyleSelector="{StaticResource cellStyle}" Width="auto" />

<telerik:GridViewDataColumn Header="Remarks" DataMemberBinding="{Binding Remarks}" IsReadOnly="True" Width="*" />

</telerik:RadTreeListView.Columns>

</telerik:RadTreeListView>

I also have a converter class to handle the DataFormatString

public class NumberConverter : IValueConverter

{

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

CellValue cellValue = value as CellValue;

if (cellValue != null && cellValue.Unit == "%")

{

return "{0:p2}";

}

else

return "{0:n2}";

}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

return value;

}

When I run these codes. it never run through the code in numberConverter class. but if i change DataFormatString code in xaml code to

<telerik:GridViewDataColumn Header="First Value" DataMemberBinding="{Binding First.Value, Mode=TwoWay}" DataFormatString="{Binding First, Converter={StaticResource numberConverter}}" IsReadOnlyBinding="{Binding First.IsEditable}" CellStyleSelector="{StaticResource cellStyle}" Width="auto"

/>

<telerik:GridViewDataColumn Header="Second Value" DataMemberBinding="{Binding Second.Value, Mode=TwoWay}" DataFormatString="{Binding Second, Converter={StaticResource numberConverter}}" IsReadOnlyBinding="{Binding Second.IsEditable}" CellStyleSelector="{StaticResource cellStyle}" Width="auto"

/>

<telerik:GridViewDataColumn Header="Third Value" DataMemberBinding="{Binding Third.Value, Mode=TwoWay}" DataFormatString="{Binding Third, Converter={StaticResource numberConverter}}" IsReadOnlyBinding="{Binding Third.IsEditable}" CellStyleSelector="{StaticResource cellStyle}" Width="auto" />

It run through the numberConverter codes. if i put a break point in this line of code
CellValue cellValue = value as CellValue;

when i checked the type of "value" from above code. instead of "CellValue" it showed "[ProjectNamespace].MainWindow" as type of value.

I followed the code from this thread
http://www.telerik.com/community/forums/wpf/gridview/dataformatstring.aspx

but it will bind the value as string and not double which causing the cell to be able to accept non numeric value.

Please suggest how to achieve this dynamic DataFormatString binding.

Thanks.
Andy

GridViewCheckBoxColumn Event Issue

box column 'GridViewCheckBoxColumn' as shown below:

<

telerik:GridViewCheckBoxColumn MinWidth="60" Width=".5*" IsReadOnly="False" Header="Select" DataMemberBinding="{Binding CHARGEWAIVEDIND, UpdateSourceTrigger=PropertyChanged}" IsFilterable="False" />

The problem I am facing at the moment is that I'm unable to find the triggering event when user changes the value of the checkbox. Currently I am using GridView's CellEditEnded event which is not suitable for this as this event triggers only when user moves the cursor away from the checkbox column. Kindly help me out.

Create Filmstrip View

Is there a way to create a filmstrip view of pictures instead of the carousel view. This is, instead of having one image come to the center top, all the images are the same size and scroll left to right, right to left.

Thanks.

Is DataServiceDataSource supported for WCF Data Services October 2011 CTP

The QueryableDataServiceCollectionView seems have a dependency on System.Data.Services.Client v 4.0. The project is built agains WCF Data Services October 2011 CTP and references Microsoft.Data.Services.Client from CTP folder. I tried to trick it with binding redirect, but it didn't work.

My version of the controls is 2011.3.1220.35. What version of WCF Data Services is supported?

Single Expand mode for HierarchicalChildTemplates?

I can't seem to find information on how to get the parent grid to only allow one row to be expanded at a time. There doesn't seem to be a way that I know of to iterate through all the GridViewRow objects in the parent grid and explicitly set them to IsExpanded = false and I don't see any property on the grid that would enable this sort of a feature automatically. It seems simple enough, maybe the developers can add that feature in for the next release? Until then though, how do I go about doing so?
